Two families, mysteriously murdered under similar circumstances, just a month apart. One was memorialized in Truman Capote's classic novel, In Cold Blood. The other was all but forgotten.

Dick Hickock and Perry Smith confessed to the first: the November 15, 1959 murder of a family of four in Holcomb, Kansas. Despite remarkable coincidences between the two crimes, they denied committing the second: the December 19 murder of a family of four in Osprey, Florida.

Over half a century later, a determined Florida detective undertakes exceptional efforts to try to bring closure to the long-cold case.

The Vampire Next Door - The True Story of the Vampire Rapist

John Crutchley seemed to be living the American Dream. Good-looking and blessed with a genius level IQ, he had a prestigious, white-collar job at a prominent government defense contractor, where he held top secret security clearance and handled projects for NASA and the Pentagon. To all outward appearances, he was a hard-working, successful family man with a lavish new house, a devoted wife, and a healthy young son. But he concealed a hidden side of his personality, a dark secret tied to a hunger for blood and the overriding need to kill.

As one of the most prolific serial killers in American history, Crutchley committed at least twelve murders, and possibly nearly three dozen. His IQ elipsed that of Ted Bundy, and his body count may have as well. While he stalked the streets hunting his unsuspecting victims, the residents of a quiet Florida town slept soundly, oblivious to the dark creature in their midst, unaware of the vampire next door.

He was a hard-working small business owner, an Army veteran, an attentive lover, and a doting father. But he was also something more, something sinister. A master of deception, he was a rapist, arsonist, and bank robber, and a new breed of serial killer, one who studied other killers to perfect his craft. He methodically buried kill-kits containing his tools of murder years before returning to reclaim them. Viewing the entire country as his hunting grounds, he often flew across the country to distant locations where he would rent a car and drive hundreds or even thousands of miles before randomly selecting his victims. Such were the methods and madness of serial killer Israel Keyes. Such were the demands of the 'Devil in the Darkness'.INCLUDES PHOTOS
